This petite cylindrical power source operates at a voltage of 1.5 volts, serving as the backbone for gadgets such as watches, calculators, small toys, laser pointers, and even certain medical instruments.

Its diminutive size, coupled with a consistent and dependable energy output, has firmly established the LR41 battery as a cornerstone in the domain of low-drain electronic devices.

Technical Specifications of LR41 battery

We often know the LR41 battery by names like AG3, 392A, or SR41, and these names refer to specific technical specifications crucial for performance and usage:

Voltage: We can count on the LR41 battery to consistently deliver a steady 1.5 volts. This voltage perfectly suits the needs of low-drain devices, ensuring they operate reliably and consistently.

Dimensions: The LR41’s design boasts a compact size, approximately 7.9 millimeters in diameter and 3.6 millimeters in height. This design allows it to seamlessly integrate into devices tailored for this specific form factor.

Capacity: While not a high-capacity cell, the LR41 battery offers a moderate capacity with a consistent voltage output, making it an ideal power source for low-drain gadgets.

Equivalent Names: Whether it’s AG3, 392A, or SR41, these different labels refer to the same reliable battery across various manufacturers, ensuring compatibility.

The LR41 battery’s technical specifications make it a dependable power source for smaller devices requiring steady and moderate energy levels. Its compact design, stable voltage output, and compatibility with low-drain electronics, such as watches, calculators, small toys, and medical instruments, make it a popular choice.

Chemistry of LR41 Battery

The LR41 battery, also known as AG3, 392A, or SR41, relies on alkaline chemistry to generate power. This chemistry involves specific components that enable the battery’s functionality:

Inside the LR41 battery, the anode consists of zinc while the cathode comprises manganese dioxide. The electrolyte, which enables ion flow, typically contains potassium hydroxide.

During discharge, oxidation of zinc within the anode releases electrons that power the device. Simultaneously, the cathode’s manganese dioxide reacts with hydroxide ions and electrons, forming water and manganese oxide.

Alkaline chemistry, used in the LR41 battery, ensures a reliable and moderate power supply, suitable for various low-drain devices. However, it’s important to note that LR41, like other alkaline batteries, operates on a non-rechargeable basis due to the irreversible chemical reactions occurring within.

The choice of alkaline chemistry in the LR41 battery strikes a balance between longevity, cost-effectiveness, and stable power output, making it practical for powering numerous small electronic devices requiring dependable and consistent energy.
